It depends on where you were sailing and what was in the water. That really mean that some of the little critters stink more and hang on better than others. I have been told that the ones that look like little shrimp, are the hardest to get out.

Most of the time soaking in soapy water and drying in open air will take care of smell. When your gear gets that dead shrimp smell especially when it gets trapped in foam, it's tough to get out, you may have to learn to live with it.

Things I have seen work at least once:

Soaking for a week in water and laundry detergent.

Soaking in your local lake for a couple of days. The theory was the lake bugs ate the death salt water bugs and now you smell like lake water. It did cut the smell

Soaking in enzymatic cleaner

Washing in PineSol. I don't know if it cleans the bugs out or if the pine smell hangs on better. It's up to you if it's better to smell like a clean bathroom or dead shrimp.
